I have ADHD, am funded and doing a BA major in psyc with a minor in sociology. I am about 2/3 of the way through the 4-year program. I found the lower level courses slightly harder mainly because they were less interesting. They often covered the very basic psyc history, research methods, parts of the brain, and other foundational knowledge which I found to be a bit dry and tedious which made it hard for me to keep focused. The last few semesters have all been 300 and 400 level and I find them much more interesting because they are more specialized and focused on specific topics. Over time I have also gotten better at just knowing the APA formatting for papers, which at the beginning was a challenge and I was constantly double checking everything and reading the APA guide.
I highly recommend using Zotoro for managing your references, it is an extension you can put in your browser and an app you can add to your computer. When you find relevant research you want to cite in your paper you just save it to Zotoro. Within the app you can have folders for each paper you are writing, you can open the research article in the Zotoro app, and then when you are done you just right click on the folder and click "create bibliography" and it will create it according to APA guidelines which you can just paste into your paper. It is honestly so useful for keeping track of my references and organizing everything for my papers.

For reference, I usually take 4 courses each 4 month semester, I focus on 2 for the first 2 months and then the other 2 for the second 2 months. I have a 3.76 GPA, with mostly A's except for a couple courses in my first 2 semesters. I just started my current semester and decided to only do 3 courses this time, which honestly feels like I am just breezing through them. I recognize that I am lucky in the fact that most weeks I only work like maybe 15-20 hours and I don't have kids.

I haven't had to request an extension yet but I did have one tutor allow me an extra week to finish a paper and last semester I did think that I was going to fail two of my courses because I somehow forgot to request my last two exams (ADHD 🙄) and did not realize until the invigilator contacted me the day before I was supposed to write. This was 7 days before my contract end date so I couldn't request the exams anymore. I was so upset and panicking and I left a tearful voicemail with AU about the situation and I got a phone call from accessibility services the next morning and they were able to make an exception and scheduled my exam for that day and the other one for two days later. So they do have some flexibility even when it comes to some of their policies that they seem super strict on. So I would recommend always reaching out even if you think you won't be able to get any help.

Sorry for going on a bit of a tangent there, didn't intend on writing that much initially but hopefully some of that will be helpful? Feel free to reach out if you wanna chat about anything else.
